Title: Alternating Cookie Ingredients

Problem Scenario

I chose this experiment because I love to bake and I thought it would be a fun science fair project to do and it would not be a boring project.

Broad Question

How do different amount of ingredients affect baked goods?

Specific Question

How will alternating two ingredients affect the mass of cookies?

Hypothesis

I think that alternating the ingredients will effect the second batch
of cookies and it will have a heavier mass.

Variables

Independent Variable: Mass

Dependent Variable: Amount of Ingredients

Variables That Need To Be

Controlled:

Amount of ingredients.

Vocabulary List That Needs Explanation

General Plan

My general plan is that I will make cookies but mix up the amount of ingredients with the flour and sugar,
instance if the flour calls for 1 cup and sugar half a cup I will flip flop the ingredients to see if it effects the mass.

Potential Problems And Solutions

There arent any big problems.

Safety Or Environmental Concerns

I will have to use the oven, but I will use oven mitts and be supervised.

Experimental Design

What is your experimental unit?

cups, tablespoons, teaspoons.

Number Of Subjects In Each trial:

2 subjects.

Number of Observations:

I will do the experiment twice.

When data will be collected

Feburary 15th.

Where will data be collected?:

At my house.
(add the correct headings from the experimental design page before beginning)

Resources and Budget Table

Item	Number needed	Where I will get this	Cost
flour	1	already have it	$0
sugar	1	already have it	$0
baking powder	1	already have it	$0
vanilla	1	already have it	$0
brown sugar	1	already have it	$0
margarine	1	already have it	$0

Detailed Procedure

1. Make a regular batch of cookies and flip flop the flour and sugar amounts.
2. Put the first batch in the oven.
3. Weigh the cookies from batch one and find a average weight.
4. Make the second batch and flip the flour and sugar ingredient amounts.
5. Put the second batch in the oven.
6. Weigh the cookies from the second batch and find a average weight.

Results

In my experiment I changed the amounts of ingredients in two batches of cookies. The first batch was just a regular batch and the average was 24.5. then I started the second batch I switched the amounts of flour and sugar so the sugar had over two cups and flour three fourths of a cup. Because there was so much sugar and not enough flour in the second batch it turned basically into brittle. I still weighed the second batch and it was an astonishing 2.6 grams average.

Conclusion
For my experiment I reject my hypothesis. I hypothesized "That alternating the amounts of ingredients in the second batch of cookies will make it have a heavier mass." I reject my hypothesis because I thought alternating the amounts of ingredients in the second batch of cookies would make the cookies have a heavier mass but instead the second batch average was a 2.6 gram average and the first batch was a 24.5 average.

Discussion

For my science project my question was "How will alternating two ingredients effect the mass of cookies?" I was able to answer my question but not in the way I expected. I thought the second batch would have a heavier mass but the first batch did. I was able to answer my question and say that when you switch the amounts of ingredients it will effect what you are baking but it really depends on what you are baking and how much you effect the ingredients.
My experiment had a few problems I was semi able to answer my question because it depends on what your baking. One of the problems was that in the second batch there was so much sugar and not enough flour that when I put it in the oven to bake it turned into a very very thin cookie and almost to a brittle. But I weighed the second batch anyway and the mass was almost a tenth of the first batch.My data could help others because it shows people that when you are baking you have to be extra careful.
My results are a benefit to society because sometimes when other people are baking items they mess up the ingredients or forget to add the ingredient to what they are trying to bake and then the person thinks "Oh its alright it will turn out the same." but it actually wont if you don't add flour like I didn't in my experiment your baked good will not rise and it will stay flat and turn out very differently than you expect.

Benefit to Community and/or Science
My project benefits the science of baking because it shows how by changing the amounts of ingredients will effect what you bake and mess up what you are baking. People always say that you have to be very precise when you bake and my project proves that if you switch up the amounts the object you are trying to bake will turn out a lot different than you are expecting.

Abstract
In my experiment I wanted to see if when I change the amounts of ingredients in cookies will it effect the mass. I baked a regular batch of cookies then I weighed them on a scale. I baked a second batch of cookies and switched the amounts of flour and sugar. I thought that the second batch would weigh more than the first but it turns out that the second batch was one tenth of what the first batch weighed.
